The caravan, which started with 200 people in Honduras, swelled in size over the weekend to between 5,000 and 7,000 migrants.

Crenshaw (R), who is vying to represent Texas' second congressional district, said that the colossal caravan "hurts the case" for illegal immigrants

"It's not sustainable from a security perspective, it's not sustainable for our education system, it's not sustainable for our health care systems," said the former Navy SEAL, who lost his right eye in an IED blast in Afghanistan.

Democratic leaders Sen. Chuck Schumer (N.Y.) and Rep. Nancy Pelosi (Calif.) released a statement over the weekend saying that President Trump is "desperate to change the subject from health care to immigration."

Crenshaw, however, said on Monday that he'd appreciate if the Democrats were honest about the debate on health care.

"God forbid we have state control over our health care," he said.

Crenshaw also said that he wants to see if the caravan dissipates before the president potentially decides to deploy the military to the border.

"In the end, we are going to enforce our laws and we are going to stop this because it's not a sustainable situation."
